36 | Description | |
37 | ----------- | |
38 | ||
39 | This driver supports hardware monitoring for National Semiconductor / TI LM25056, | |
40 | LM25063, LM25066, LM5064, and LM5066 Power Management, Monitoring, Control, and | |
41 | Protection ICs. | |
42 | ||
43 | The driver is a client driver to the core PMBus driver. Please see | |
44 | Documentation/hwmon/pmbus for details on PMBus client drivers. | |
45 | ||
46 | ||
47 | Usage Notes | |
48 | ----------- | |
49 | ||
50 | This driver does not auto-detect devices. You will have to instantiate the | |
51 | devices explicitly. Please see Documentation/i2c/instantiating-devices for | |
52 | details. | |
53 | ||
54 | ||
55 | Platform data support | |
56 | --------------------- | |
57 | ||
58 | The driver supports standard PMBus driver platform data. | |
59 | ||
60 | ||
